Specification of Letters Patent.

Patented May 25, 1915.

Application filed February 25, 1915. Serial No. 10,571.

To all whom it may concern:

Be it known that I, ELBERT G. CHANDLER, a citizen of the United States, residing in the city of Portland, county of Multnomah, and State of Oregon, have invented certain new and useful Improvements in Logging- Trucks, of which the following is a specification.

My invention relates to logging trucks, such as are used in pairs for hauling long logs, one truck being placed under each end of the log. It is quite common for these logs to be as much as ninety feet long, and because of their length, and the distance between the trucks, which must necessarily beplaced near the ends of the logs, said logs sag in the middle sometimes low enough to almost engage the track. Because of this sagging, the logs frequently engage and rest upon the inner ends of the truck frame, and the draw-bar thereof, and thus operate to prevent the trucks from turning under the logbunk thereupon, which frequently results in the derailment of a truck.

The object of my invention is to provide such an improvement in logging trucks, which are used in pairs at the opposite ends of long logs, that no matter how much the logs sag between the trucks, they will not engage the truck frame, nor the draw-bar thereof. I accomplish this by constructing the trucks so that the draw-bars at the outer ends thereof are at standard height, and are adapted to be coupled to the draw-bars on standard railroad equipment, while the draw-bars on their inner, or adjacent, ends are positioned considerable lower than are the outer draw-bars, thus giving clearance for a log resting upon the car-bunks, to sag to the limit without interfering with the inner ends of the trucks or the inner drawbars. a

When returning the logging trucks empty, they are, of course, readily coupled together at their inner ends, because at their inner or adjacent ends, the draw-bars,-while lower than the standard draw-bars, are of substantially the same height and can be 0011 led together, while the draw-bars at their outerends are standard .height.

in order that others may thoroughly urn derstand my invention, I have shown in'the accompanying sheet of drawings, one practidal embodiment bf the invention, which I v yfili nowdescribe. 1 -d wings, I'haveshbwn inside l 6. In combination vation a pair of logging trucks with a long log supported thereon at its opposite ends, with two portions thereof broken out, .to reduce the length of the figure, but showing the middle portion in substantially the position it would occupy, sagging almost to the track, as is common where these very long logs are thus supported.

In the drawings one truck is designated A, and the other truck is designated B. Each is provided with a log-bunk,'as A and B adapted to turn upon the truck in the usual manner, and upon which the opposite ends of the log rest, substantially in the manner indicated. Each truck is provided. at its outer end with a draw-bar, as A and B of standard height so as to be coupled into a regular train, and each is also provided on its inner end with a draw-bar, as A and B positioned considerably lower than the outer draw-bars, but adapted to be coupled together when the trucks of each pair are brought together to be returnedempty.

So far as 1 am aware, I am the first to provide a pair of logging trucks having their draw-bars at their outer ends at standard height, and having their inner ends constructed low to give clearance for the sag-' ging of the logs placed thereupon, with their inner draw-bars also below standard, to avoid interference with the sagging log, and thus to avoid the serious objection of the logsengaging and resting upon the inner' ends of these logging bunks, and the inner draw-bars, and interfering with their following the track upon which they are to run.

What I claim and desire to secure by Letters Patent is,

1. A pair of logging trucks havin at their outer ends draw-bars at standard height, and having at their inner ends, draw-bars arranged below standard height, whereby to give clearance for sagging logs thereon, and at the same time being adapted to be coupled to each other, when said trucks are brought together; I

2, A logging truck having a log supporting bunk thereupon, and provided at one end with con ling mea'nsat substantiall standard heig t, and at it'other end wit coupling means considerably below standard height, substantially as and for the purpose indicated. 4

two logging trucks,

rec

- each provided with log supporting means,

and each having at its outer ends coupling .Ineanspositioned at substantially standard height, whereby to be coupled to standard equipment, and each having at its inner end ing means positioned below standard coup height, whereby" to give clearance, and adapted to be coupled together.

43A- logging truck having a log bunk pivotally mounted thereupon, a draw-bar at one end mounted at standardheight, and

adapted to be coupled to standard railroad equipment, and a draw-bar at the opposite end of said truck below the top of the frame thereof, and below standard height, to give 15 clearance forwardly of the log. bunk, substantially as, and for the purpose described. Signed at Portland, Multnomah county, Oregon, this 19th day of February, 1915.
